A Provided is a communication device that includes a plurality of antenna units that are arranged in an array. Each of the antenna units includes a first antenna element and a second antenna element that are arranged in a first direction, a first receiving unit that receives a first wireless signal used in satellite positioning, via the first antenna element, and a second receiving unit receives a second wireless signal used in the satellite positioning, via the second antenna element. Among the antenna units, a first and a second antenna units that are positioned adjacently to each other in a second direction being perpendicular to the first direction are arranged in such a manner that the first antenna element in one of the first and the second antenna is positioned adjacently to the second antenna element in the other antenna in the second direction.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The communication device according to claim 1, further comprising a receiver clock configured to detect a timing at which the first wireless signal is received by the first receiver, and a timing at which the second wireless signal is received by the second receiver.
5. The communication device according to claim 4, wherein the receiver clock is shared between at least two antennae the plurality of antennae.
7. The information processing apparatus according to claim 6, wherein the CPU is further configured to estimate the carrier-related information, based on a code pseudo-range and a carrier phase of each of the first wireless signal and the second wireless signal.
8. The information processing apparatus according to claim 7, wherein the carrier-related information includes at least one of an initial carrier bias or an initial carrier phase bias.
9. The information processing apparatus according to claim 8, wherein the CPU is further configured to calculate the initial carrier phase bias of at least one of the first wireless signal or the second wireless signal based on a remainder of dividing the initial carrier bias of corresponding wireless signal by a wavelength of the corresponding wireless signal.
11. The information processing apparatus according to claim 6, wherein, based on the reception results of the first wireless signal and the second wireless signal received by, using one of the first antenna element and the second antenna element as a reference, each of a plurality of other antenna elements arranged in different directions with respect to one antenna element, an error in at least one of a tropospheric delay and an ionospheric delay included in the reception results received at each of the other antenna elements is cancelled out.
